Abstract

Amorphous WS₂ has been prepared by ultrasound irradiation of W(CO)₆ solution in diphenylmethane (DPhM) in the presence of a slight excess of sulfur at 90°C under argon. Heating the amorphous powder at 800°C under argon yields WS₂ nanorods and their packings. The average size of WS₂ nanorods was found to be 3-10 nm and 1-5 μm in thickness and length, respectively. The prepared WS₂ has been characterized by elemental analysis, X-ray powder diffraction measurements, FTIR spectroscopy, differential scanning calorimetry, thermogravimetric analysis, transmission electron microscopy, scanning electron microscopy, atomic force microscopy and energy dispersive X-ray analysis.
